P: Program error when saving, lag when zooming, changes not reflecting in document window (macOS)

Have encountered problem after problem when trying to save files, change brushes, merge layers. All give me a popup window titled program error. Have found a loophole around it where if you turn off all the layers besides the bottom most one and save it can. However, still unable to work and view the physical final files to save as PNG's and JPEGS for use and for clients. Photoshop has become utterly useless. 

having the same issue here. 

So the offered early access is now moot.

Install the 22.1.1 update that went out late last night/early this AM. It has fixes for program errors.

Different user. Same problem. Update 22.1.1 doesn't fix continuous program errors when exporting, flattening, or duplicating. Cannot save any files.

``One thing though, that I can't understand why adobe not giving us an update which is reverting the latest until they finding the problem''

You aren't the only one wondering that. 😞

@Shaun Kendall If you can, yes please.  Any and all feedback is appreciated.

Would you like us to report back if it has alleviated the issues we were having? 

@bkorb @andrew_sender 
by hobbyist I meant that I'm not use ps on professional. Right now I have many photos to edit, but not working with ps daily. That's why I said that someone can use this oppurtinity more.
Now I understand what Jeffrey said that it's not that easy to reproduce the problem, bc can't follow when I run into and when not.
Since it's not limited so if I can help, than thx for the add, and will try to be use.
One thing though, that I can't understand why adobe not giving us an update which is reverting the latest until they finding the problem, they can do a public/large wide test too. 
So thx andrew if You can add me, I will try to help
